You are a real estate broker and your clients always ask about utility costs when they are considering a new home for purchase. You decide to use your analytical skills to build a model that will enable you to predict the amount of the electric bill for a particular location based on a number of different factors. You have collected data and summarized it in a spreadsheet. In addition to the amount of the monthly electric bill, you have information on temperature, the number of days when the heat or air conditioner might need to run, whether or not a new meter or heat pump has been installed, and total energy consumption.

Question

After several iterations, you arrive at Model which includes the predictors: TEMP, SIZE, METER, PUMP1, PUMP2. Suppose that you decided to add a new heat pump 2 (holding all other things constant). How would you expect the electric bill to change (The expected change in bill amount by adding a new heat pump 2)?
